What is the primary function of control instruments in aviation?

The primary function of control instruments in aviation is to display attitude and power. These instruments are essential for providing pilots with real-time information about the aircraft's orientation relative to the horizon (attitude) and its engine power settings. This information is crucial during various phases of flight, particularly during takeoff, landing, and maneuvers, where maintaining proper attitude and understanding power settings can directly impact the safety and control of the aircraft.

Control instruments include the attitude indicator, which shows the aircraft's position in the three-dimensional space relative to the horizon, and the power instruments, such as the tachometer or engine power indicators, which inform the pilot how much thrust the engines are producing. By displaying this vital information, control instruments help pilots make informed decisions that affect the operation and safety of the flight.
